5 Claims.

This invention relates to the construction of display shelving units andparticularly to the use of clamp brackets for adjustably supportingshelf members in connection with a peripheral supporting plate or panel;and the object of the invention is to provide a clamp bracket involvingtwo similar channeled clamp plates and a coupling rod or screw inthreaded engagement with one or said plates for drawing the sametogether to secure a shelf member in connection with a vertical panel; afurther object being to provide bracket plates or the class describedhaving arc-shaped or channel-shaped panel and shelf engaging portionsarranged at an angle of substantially forty-five degrees to each otherto provide for the inclined mounting of a shelf plate or panel inconnection with a vertical panel; a further object being to provide abracket plate of the class described involving a plurality of angularlydisposed channel portions arranged at forty-five and ninety degrees withrespect to each other to provide for the mounting of shelves uponopposite side surfaces of a vertical panel;

iii

a further object being to provide in a unit of the class described meansin the form of a channeled base plate for supporting the vertical panelupon a table, counter or other supporting surface; and with these andother objects in view the invention consists in a display unit and clampbracket construction more fully hereinafter described and claimed.

The invention is fully disclosed in the following specification of whichthe accompanying drawing forms a part, in which the separate parts of myimprovement are designated by suitable reference characters in each ofthe views, and in which:-

Fig. 1 is a perspective View showing one assemblage of units which I mayemploy with parts of the construction broken away.

Fig, 2 is a side and sectional view of a part of the construction shownin Fig. 1 on an enlarged scale; and,

Fig. 3 is a partial section on the line 33 of Fig. 2 with part of theconstruction broken away.

In Fig. 1 of the drawing, I have shown for the purpose of illustratingone method of carrying my invention into effect, one form of shelvingdisplay unit and, in said figure, 5 represents a vertical plate or panelpreferably composed of glass of the annealed and substantiallybreakproof type, and this panel may be of any desired height and Widthdepending entirely upon the use thereof .and the type of articlesor.merchandise to be displayed thereon; and while the ar- 1936, SerialNo. 93,610

rangement of inclined shelves 6 and l and horizontal or right-angledshelves 8 and 9, shown in Fig. l of the drawing, will illustrate apossible arrangement of shelving, it will also be apparent that anydesired arrangement of shelves and spacing thereof may be employed. Forexample, the unit may include all inclined shelves on one or both sidesof the panel 5 or any desired arrangement of horizontal and inclinedshelves.

For example, at Ed I have shown a part of an inclined shelf at theopposite side of the panel 5 with respect to the shelf 65 and anotherin- 'clined shelf 6b opposite the shelf 8; whereas, at So I have shown ahorizontal shelf opposite the shelf 9. At it, I have shown a flange orretaining strip disposed at right angles to the lower edge of the shelf5, and at [Ed I have shown. a similar strip arranged at an angle offorty-five degrees to the shelf 1 or, in other words, in a perpendicularplane, whereas at Hlb, I have shown a similar strip at right angles tothe horizontal shelf 8.

The above described different arrangements of shelving are made possibleby the use of a plurality of pairs of clamp brackets consisting of clampplates l2 of the forty-five degree angle type; plates I3 of the ninetyor right-angled type; plates 14 of the double, forty-five degree type;plates 15 of the combination of ninety and fortyfive degree types, andplates !6 of the cross or four-way, ninety degree type. At this time, itwill be understood that by inverting the position of the forty-fivedegree angle display, shelves may be arranged in an upwardly inclinedposition to form bins or pockets but this type of construction is notoften used, and therefore, is not illustrated.

Each of the clamp bracket units is of the same general construction, andtherefore, the brief description of one unit will apply to all. In Figs.2 and 3 of the drawing, I have shown in detail, for example, the unitsl2, and these units are provided with angularly disposed semi circularor channeled portions ll--ila joined by a web plate l8 through whichcoupling rods or screws 19 are passed. The head 2% of the screw l9engages one plate in each pair, whereas the threaded end portion 2 l ofthe screw engaging a drawn or extended threaded bearing portion 22 onthe web plate I8 of the other plate in said pair so that the rotation ofthe screw l9 will operate to draw the units l2 together to engage theedge portion of the upright panel 5 and the shelf H in the constructionshown. It is preferred that pads 23 of cushioning material be arrangedupon the inner surfaces of the channeled portions l1 l'la so as not toinjure the edges of the supports 5 and 1, especially when the latter arecomposed of glass.

The foregoing also applies to the mounting of the flange or retainerstrip Illa in connection with the lower edge of the shelf 1 as isillustrated in Fig. 2 of the drawing.

As above stated, it will be understood that each shelf may be adjustablyclamped in the desired position upon the support 5 by the screws passingthrough the respective pairs of clamp bracket plates.

It will be understood that where the dual or two-way brackets areemployed, as for example, at l4, l5, and IS, the shelf at one side ofthe upright panel 5 will be adjusted temporarily in position after whichthe other shelf will be placed in position and then both shelves firmlysecured in position by tightening the screws. It will also be apparentthat where different arrangements of shelves are desired on oppositesides of the upright panel 5, independent clamp brackets or pairs ofclamp plates will be employed.

In mounting the upright panel 5 in connection with a supporting surface,I employ a channeled supporting plate 24 which is provided with anupwardly directed channel portion 25 in which the lower edge of thepanel 5 is firmly supported and, in the construction shown, the plate 24extends widely at the side 24a and has a narrow extension on the side241), which is designed primarily for a one-sided display to be arrangedat the rear of a counter or similar supporting surface, but when bothsides of the upright panel 5 have shelves arranged thereon, it will bepreferred to have the plate 24 extend equal distances, at both sidesurfaces of the channel portion 25, the'extensions 24a and 24?) areapertured, as seen at 26, to receive screws or other fasteners to securethe same to a support. It will be understood, in this connection, thatother types of supporting means may be employed for the lower endportion of the panel 5, it being preferable to use some type of achannel mounting to facilitate the attachment and detachment of thepanel 5 in the operation of cleaning the display or in changing theshelf arrangement thereon.

It will be understood that by constructing the entire unit of glass, avery attractive as well as readily cleanable display shelf unit isprovided and furthermore one which is flexible in its arrangement ofshelving vertically thereof as Well as angularly with respect to thevertical supporting plate.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is.
